Professor Lee has research interests in labor economics, econometrics, and political economy. He has worked on issues of inequality in the labor market, and has also worked on the analysis of elections, and how they can be used in quasi-experimental empirical analysis of the impacts of unions in the labor market, and policy convergence in Congress. Lee continues his work on inequality- and poverty-related issues, focusing on youth criminal behavior, and the impact of the minimum wage, as well as on econometric methodologies appropriate for analyzing experiments and quasi-experiments. He received his Ph.D. from Princeton, and has previously held appointments in economics departments at Harvard, Berkeley, and Columbia.
